  • Patent number: 6681776
    Abstract: An apparatus for wrapping hair strands with string or artificial hair is disclosed. The apparatus has a shell that defines an axle having an opening. The axle rotatably supports a drive wheel, a spool of string and a guide wheel. The drive wheel engages the guide wheel. The string passes from the spool past the guide wheel, which has circumferential notches to engage and play out the string. In practice, the user passes a hair strand through the opening in the axle, fastens the string to a hair strand, energizes the apparatus, and moves it along the length of the hair strand as the string is wrapped about the strand. The apparatus is preferably powered by a small DC motor.

  • Patent number: 6164289
    Abstract: A hair braiding apparatus is disclosed comprising a two arms for receiving hooks. The hooks hold a first and second strand of hair, respectively, in slideable engagement and can be retracted and extended by the operator. A third stand of hair is braided with the first and second strands as the arms and books are caused to automatically rotate cyclically and reverse their previous positions. The cyclic rotation carries the first and second strands with it and produces a braid as the operator moves the third strand upward and downward through the opening defined by the arms and the first and second strands. The apparatus may be powered by a DC motor.
